The motor neuron and the muscle fiber it controls constitute a what?
The motor neuron and the muscle fiber it controls constitute a motor unit. This functional unit is essential to the process of muscle contraction and movement in the body. When the motor neuron sends signals to the muscle fiber, it results in the activation and coordination of muscle fibers to produce movement.
What are the 3 structural components of a neuromuscular response?
The three structural components of a neuromuscular response are the motor neuron, the neuromuscular junction, and the muscle fiber. The motor neuron transmits signals from the brain or spinal cord to the muscle, the neuromuscular junction is where the motor neuron and muscle fiber meet and communicate, and the muscle fiber is the contractile tissue that generates force in response to nerve signals.
The synapse of a motor neuron with a muscle fiber is known as the what?
neuromuscular junction
What site where the motor neuron and muscle cell meet is called the?
The site where a motor neuron and muscle cell meet is called the neuromuscular junction. This is where the motor neuron releases neurotransmitters that signal the muscle cell to contract.
What is the function of motor end plate?
A motor endplate is a large special synaptic contact between motor axons and each skeletal muscle fiber. Each muscle fiber forms one endplate. Its function is to transmit impulses from nerves to muscles.

When the motor neuron sends signals to the muscle fiber, it results in the activation and coordination of muscle fibers to produce movement.
A motor neuron together with the muscle fiber it innervates?
it is the motor unit
How is a skeletal muscle fiber stimulated by a motor neuron?
motor unitUnit
Does each skeletal muscle fiber has one neuromuscular junction?
Yes, each skeletal muscle fiber has one neuromuscular junction (NMJ) where a motor neuron connects to the muscle fiber. This junction is the site where the motor neuron releases neurotransmitters, specifically acetylcholine, to stimulate muscle contraction. While a single motor neuron can innervate multiple muscle fibers, each individual muscle fiber receives input from only one motor neuron at its NMJ.
What is the name of the point at which motor neuron synapses motor end plate?
The point at which a motor neuron synapses with a muscle fiber's motor end plate is called the neuromuscular junction. This is where the nerve impulse is transmitted from the motor neuron to the muscle fiber, leading to muscle contraction.

Each skeletal muscle fiber is controlled by a motor neuron at a single?
neuromuscular junction
What is the function of the neuromuscular junction is to?
Includes the axon terminal of a motor neuron plus the motor end plate of a muscle fiber. Is where the axons of motor nerves meet the muscle & transmit messages from the brain which cause the muscle to contract & relax.
Where does a motor neuron send its message?
A motor neuron sends its message, in the form of an electrical signal called an action potential, to a specific muscle to stimulate contraction. This signal travels down the neuron's axon to its terminal branches, where neurotransmitters are released to activate the muscle fibers.
